Chronic disease is disease that persists for periods longer than six months and it doesn't resolve itself in a short amount of time.
Examples of chronic diseases are: diabetes, Alzheimer's disease, hypertension, asthma, AIDS, autoimmune diseases, etc. In children, asthma is the most common chronic disease.
Chronic diseases accompany the individual for a relative period of their life and, in many cases, there is no cure, only periodic treatments, thus becoming an aggravating factor in the well-being and quality of life of the individual.
Although a chronic disease is not an emergency, it can be extremely serious in certain respiratory diseases, cardiovascular diseases, among others.
In some cases, chronic diseases are asymptomatic (the carrier does not have any symptoms), but when they manifest, crises can be intense, painful and very uncomfortable.
In general, chronic diseases cannot be resolved with just a drug, they require more treatments, as is the case with infectious diseases or diseases such as AIDS, Alzheimer's disease, etc.
